Answer:
(a) 39,208
(b) 65%
Step-by-step explanation:
(a) The car loses 10% the first year and 15% the second year so that’s 35% lost in total after two years.
35% of 60,320 is 21,112
60,320 - 21,112 = 39,208
39,208 ÷ 60,320 = 0.65 (65%)
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
= 3(x^2 + 8x) + 43
= 3(x^2 + 8x + 4) + 31
= 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex
